This invention relates to improvements in window assemblies. It is illustrated in a door structure provided with'a window and screen assembly. It is adaptable for use in any suitable window assembly whether the same is embodied in a door or in a window frame designed for stationary placement in the wall of a building.

The invention relates particularly to a window assembly which includes a window frame provided with a pair of window sashes and a screen capable for use in substitution for either window sash and wherein the screen or window sash, whichever is not in use, may be conveniently stored alongside of or overlying the other window sash which is inuse, and wherein the construction is such that placement for use or removal or storage may be quickly and conveniently made. The invention is embodied in a construction consisting of a window frame and sash formed of sheet metal and is particularly designed for this v provided.

An object is to provide a window assembly of the type described comprising a window frame formed of sheet metal which can' be readily secured to supporting window or door frame structure and which has associated therewith upper and lower window sash and a screen sash also formed of sheet metal capable of substitution for either the upper or lower window sash and for storage within the boundaries of the assembly.

Another object isthe provision of an assembly .of the character described wherein one of the window sash, as for example the lower window sash, is mounted within the frame in the usual Ywindow runwayvand the cooperating sash, such as the upper sash, is held in place by means which provides a weathertight seal, but also per- .mits quick removal of the sash and insertion of a substitute sash in position therefor. i The means `for holding the readily removable sash in place and for facilitating its replacement is simple and inexpensive and .also permits convenient displacement of the sash to a ventilator position.

Another object is the Vprovision of an assembly s of thekind described of a storage space for the Vsash not in use disposed Within the boundaries of 2 the assembly and wherein the stored sash is protected.

The construction is also of such a character that the sash elements may be placed within'the frame structure for shipment and will occupy a minimum amount of space.

Other objects, advantages and important features will more fully appear from the following description, claims, and accompanying drawings, wherein:

Fig. 5 is a horizontal sectional View partly broken away taken on the line 5 5 of Fig. 1;

Fig. 6 is a horizontal sectional view partly broken away throughthe upper portion of a window assemblysuch as Fig. 1 showing the upper Window sash displaced for ventilation;

Fig. 7 is an elevation similar to that of Fig. 1 showing a modiiied construction; y

Fig. 8 is a sectional view taken on a line such as 8-8 of Fig. 7 showing disposition of the sash within the frame for shipment and with an additional screen sash assembled therewith; and

Fig. 9 is a sectional view taken on the same line as Fig. 3 through a construction such as Fig. 1 showing the screen sash in superposition above the lower window sash and the upper window .dow frame assembly. This window frame as sembly includes a pair of cooperating frame side rails 2l! which may be formed of wood and covered on opposite sides by metal sheets 22. There is a header portion for the frame also shown as formed of wood indicated as 24. This wood frame portion is covered by metal sheets 26.

There is a sill frame portion 28 covered by metal sheets 3D.

Vlower margin of the glass pane.

The above construction forms merely the environment for my improved window frame assembly. The window frame assembly itself consists of a pair of upright side frame members 32 shown particularly in Figs. 1, 2, 4 and 5. E'ach side frame member is formed of sheet metal shaped to define a channel portion the side walls of which are folded over as shown in Figs. 4 and 5, and which channel portion is adapted to seat over the metal sheathed uprightmembers 20 as shown in Figs. 2, 4 and 5. Each of these frame members 32 is so shaped as to denne a flange 34 which constitutes one side wall of a window guideway and against which the window sash rests. The header member 3S of my window assembly is shown particularly in Fig. 3 and it is formed of sheet metal and exhibits a channel portion which is adapted to be received over the metal sheathed header 24. One of its side Walls is doubled over on itself and extended inwardly to form one side wall38 of an upwardly opened window sash receiving header channel. The other side wall of this upwardly opened window sash receiving header channel is formed by an angular member 48. One angular portion of this member 40 indicated as 42 is received underneath a part of the side wall 33 as shown in Fig. 3.

The sill portion of the frame is formed of sheet metal shaped to define a downwardly open channel 44 as shown in Fig. 3 which channel is adapted to be received over the metal sheathed sill member 28. One side wall of this channel 44 isfolded back upon itself as at 45 and over the bottom of the channel and then upwardly forming a lip 48 which constitutes an inner side wall against which the lower window sash rests as shown in Fig. 3. This window sash is held against this inner side wall 48 by the side Walls 34 of the vertical rails of the frame heretofore described.

There is mounted within this frame assembly a lower window sash 50 and an upper window sash 52 and a screen 54. Each window pane is bounded by metal sash as shown. The meeting rails of the metal sash are peculiarly formed to vinsure interengagement of the two window sashes as shown in Figs. 2, 3 and 8. The header rail of the lower window sash is indicated as 58.

rattle.

The meeting rail of the upper sash is formed of sheet metal and is shown as engaging the One side wall of its channel 62 is folded over upon itself as at 64 forming a flange that normally lies flat against such side wall, but this flange is adapted to be swung resiliently outwardly as shown in Figs. 2 and 3 so as to receive thereunderneath the flange 58 of the meeting rail of the lower sash. This forms a weathertight joint. It also interlocks the sash together along their meeting rails so as to assist in retaining the upper sash in position. The opposite side wall of this channel 32 is folded outwardly upon itself forming a relatively narrow iiange 66 spaced from the side wall and adapted to serve as a handle as shown in Figs. 2 and 3. The upper and lower sash each bear against the 'metal frame extending thereabout. 'frame which extends about the screen is formed guide wall 34 of the side rails of the frame. This is true as to the door structure shown in Figs. 1 through 6 and the window structure shown in Figs. 7 through 8. These two structures are substantially the same except for slight variations to suit window and door conditions hereinafter specically referred to.

The lower edge of the lower window sash is provided with a channel shaped sill member 68. One side wall of this sill member is folded over upon itself as at 'I0 as shown in Fig. 3 to overhang the upright ledge 48 of the sill portion of the frame and to also form a hand lift portion.

The upper margin of the upper sash is provided with a header section formed of sheet metal and indicated as T2 which is channel shaped and seats over the upper margin of the glass pane. One side wall of this channel shaped member is folded over upon itself as at 14, as shown particularly in Fig. 3. When the two sash are disposed in superposed relationship as shown in Fig. 3, the header section of the upper sash does not extend to the top of the channel in the header of the frame,` It is noted that there is a space in Fig. 3 above the top of the upper sash within the header channel of the frame and this upper sash may be lifted within this space, the ange 14 passing over the lip 38. This permitted elevation of the upper sash is suicient to disengage the meeting rails of the upper and lower sash.

The lower sash is held in place against the side wall element 34 of the upright rails of the frame by one side wall of a channel member 16. This channel member is shown particularly in Figs. l, 2 and 5. It may be secured in place by nails 18 driven through its bottom portion and into the wood side rails 20 of the foundation of the frame as shown in Fig. 5. This channel member is shown as of a shorter length than the vertical height of the lower` window sash. Its inner side wall forms together with the side wall 34 a guideway for the lower window sash. This inner side wall is bent inwardly and folded over as at 8D so as to denne a relatively narrow guideway within which the screen 54 may be stored as shown in Fig. 5. Y

The upper sash is held against the side wall 34 when its meeting rail is engaged with the meeting rail of the lower sash as shown in Fig. 3 by virtue -of such engagement and also by virtue of the fact that its header is received within the header channel of the frame as shown in Fig. 3 and as vpreviously described, but it is also held against such side wall 34 by rotatable retaining elements 84. These retaining elements are in the form of pins as shown particularly in Figs. 2 and 4 extending throughv the upright 'frame members and into the wood side rails 20.

The outer ends of these pins are `bent over as at 8E so that in the position shown in Fig. 4 these outer ends bear resiliently against the upper sash holding it against the guide wall 34. It is apparent that when these pins 84 are rotated through an arc in excess of 90 (note Fig. 6), the upper window sash may be moved laterally within the frame and such movement is sufficient to permit disengagement of the meeting rails of theY two sash providing the upper sash is lifted to accomplish such disengagement.

The screenv is illustrated as provided with a The metal along one edge shown as the sill portion in Figs. 3 and 9 to correspondv with the formationof the .sill portion of theupper window showninv Fig.

3; This portion ofthe screen'frame has a ange section. 88 which projects below the edge of the screen frame proper. As shown inFig. 1, this 'sill member has alength less than the width of the screen so that it will not interfere with movement of the screen into the guide channel 76. Its width is such, however, that. when the screen is seated upon top of the lower window sash as shown in Fig. 9, the two meeting rails are interengaged. When the screen is in storage as shown in Fig. 3, this iiange portion engages the sill of the window frame assembly.

The -arrangement is such that when the two window sashes are superposed `as shown in Fig. 3, the' screen may be stored within the channels T6 as shown in such gure. The projecting flange `Bil of the head of the lower window sash is shown bearing against the screen sash to assist in holding it snugly in place. The inturned portions 80 of channel 16 form withv the opposite side wall of the channel `a narrow guide within which the relatively thin screen frame is supported. When it is desired to install the screen in the upper portion of the window opening above the lower window sash, the screen may beremoved from its stored position. The retaining pins 84 will then be rotatedto permit the upper window sash to Ybe moved laterally after having been lifted. It can be moved laterally to completelyidisengage its meeting rail from the meeting rail of the lower sash and then lowered into the channels 1E for storage. The screen can then be placed in the upper portion of the window opening above the lower window sash and its meeting rail engaged with the meeting rail -of the lower sash as shown in Fig. 9.

The stationary window construction shown in v Figs. '7 through 9 is substantially the same as the door window construction shown in the first six iigures of the drawing except that the screen storage channels 16 are mounted in the upper portion of the window opening and the rotatable retaining elements 84 are mountedin the lower portion of the window opening. This is an alternative `arrangement as that shown and y described heretofore. Either form may be used. Fig. 8, however, shows the wood sill of the stationary window frame as having a outer metal strip of angular shape identified as 90- secured thereto and overlapping the outer wood sill 92 of a conventional window frame.

If it is desired to provide a limited amount of ventilation without inserting ya screen above the lower window sash, this may be accomplished by moving the upper window sash tothe position shown in Fig. 6. It is apparent how this can be done. This will provide a limited opening and the upper window sash is supported upon the flange lfil) of the header portion of the lower window sash -between said sash `and the upper margin of the screen and it rests against the window retainers 84. In Figs. 7, 8 and 9 the frame provides a storage space for the screen at the top instead lof at the bottom. The construction is otherwise as heretofore described in Figs. 1 to 6. The screen is shown as stored Vat the top in Fig. 8. The screen is of light weight and the walls of the channel 'F6 grippingly `engage the screen so as to hold it elevated. When so stored it is inverted and the `sill portion in Fig. 3 is shown at the top in Fig. 8.

The construction is such that a weathertight seal is formed and the windows cannot be opened from the outside.

Fig. 8 shows one means whereby a window assembly could be arranged for shipment andan additional screen shipped with the. assembly hereinabove described. The -additionalscreen is indicated as 96. It would lie substantially within the boundary of theassernbly frame.
